Title: Adds support for raycasting with morphs

This isn't insanely fast, but it stops the bug described here, where the RayCaster assumes all meshes are in their unmorphed form.

Tested on a mesh with 10000 vertice, runs at a reasonable speed. The code path should only be taken if morphs are enabled anyway.
